Acoustic Sensors

Experimental Acoustics - Our scientists and engineers have extensive experience in conducting both laboratory and at-sea measurements, and in analyzing and interpreting the acquired data. Several facilities are available for conducting controlled freshwater experiments: the Acoustic Test Pool (nonmagnetic), the Acoustic Test Facility, and the Physical Acoustics and Special Projects Laboratories. Experiments can be done on scale models to full-scale vehicles. Controlled sea measurements utilize a 6-foot high stationary sonar tower. It is deployable by divers in any water depth less than 20 feet, has vertical tilt and horizontal pan motors, and can accommodate several sonars or other pieces of equipment at one time. This tower has been used in the past to measure various acoustic parameters of targets, water, and sediments, and for assessing competing sonars. Our personnel can plan and carry out the entire test, from preliminary environmental impact statements and safety plans, to the scheduling of craft, divers, and riggers, in addition to complete post-test analyses.
